The Original Glowstars Company Glow Window Art

This was a gift and so I have not seen it used but I do know that it was very enthusiastically received by by 10 year old great niece.

The kits are easy to setup, even did some of my own templates, bought these to cover a large glass door that a delivery driver decided to put his knee through. I figured, did these as a kid, were fun, fills some time, decorate the door, door more obvious at all times of the day.They don't glow in the dark... At all, like, not even faintly. I've had a template on a full-sun window for a few days now, not a single glow.For the cost, kind of expected a few more tubes.Some templates have gaping holes in them after drying where the colour didn't bond with the black outline during the 10 min activity.The contents of the tubes seem to dry out pretty quick after first use, regardless the lid was slapped back on. Subsequent templates there after contained a lot of bubbles, clumpy liquid etc.Is there any real point to a screw-thread nozzle cap? With a small amount of force (for example, trying to squeeze half-dried solution out of them), the nozzle flies off.
